DlAPHRAGlVl-PUWIR SPECIFICATION forming part of Letters Patent No. 599,273, dated February 15, 1898.

` Application filed July 17, 1897. Serial No. 644,981, (No model.)

To all wiz-om, t may concern:

Be it known that I, NESTOR ALBIN WAH- TOLA,a citizen of the United States, and a resident of Ironwood,in the county of Gogebic and State of Michigan, have invented certain new and useful Improvements in Diaphragm- Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac-` companying drawings, which form a part of this specification.

My invention relates to diaphragm-pumps of that class or description which comprise in their structure a stationary pump-tube, a series of stationary partitions provided with ports, passages, and valves, a series of vertically-movable cups and diaphragms connected with said cups and partitions, the construction being such that as the cups are reciprocated water will be forced upward upon both the upstroke and downstroke of the same.

The invention consists in the novel construction and combination of parts, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal section of a pump constructed in accordance with my invention on the lines 0o o0, Figs. 2, 3, 4, 6, S, and 10. Fig. 2 is a perspective view looking from the upper side of the lower section of the partition of the lower cups. Fig. 3 is a similar view looking from the under side of the central section. Fig. 4 is a similar View looking from the upper side thereof. Fig. 5 is a similar view looking from the under side of the upper section, also showing the double pump tube or barrel and the lower section of the partition of the intermediate cups. Figs. 6 and 7 are perspective views of the central and upper sections thereof. Figs. 8 and 9 are perspective views of the sections comprising the partition of the upper cups. Fig. 10 is a plan view of the lower section. Fig. 11 is a view looking from the under side of the upper section. t

In the said drawings the reference-numeral 1 designates the upper pump tube or barrel, and 2 the lower tube or barrel. The lower and upper ends, respectively, are secured to stationary circular partitions hereinafter described.

At the upper end of the upper tube 1 is an air-chamber 3, provided with a spout 4 and a turning plug or cock 5. The numeral 6 designates a bracket secured to said tube, with which is pivotally connected a yoke 7, provided with a handle 8, and pivotally connected with said yoke is a rod 9, the lower end of which is pivoted to a lug 10 of a verticallymovable cup or section 12. This section, which is semispherical in shape, is provided with a central opening through-which said tube 1 passes and is connected with a similar but inverted cup 13 by means of bolts 15, which pass through iianges 16 on said cups.

Connected with the cup 13, by means of rods 17, is a cup 13, connected by means of bolts 19 with a cup 20. These cups 13 and 2O are identical with cups 12 and 13, and cup 2O is connected by rods 21 with a cup 23, connected by 4bolts 24 with a cup 25, also similar to cups 12 and 13. rllhe lower tube 2 passes through cup 25, while a double or two-part tube, hereinafter described, passes through cups 13 and 18, while a similar tube passes through cups 20 and 23. The cups where said pipes pass through are provided with stuffing-boxes 26 to make tight joints.

Secured to the lower tube 2 and located within the cups 23 and 25 is a stationary partition made in three parts bolted together by bolts 27 and formed with water ports, pas-` sages,and valves hereinafter described. Similar partitions, but slightly different in construction, are located on the cups 1S and 20 and 12 and 13, and confined between the iianges of said cups and upper and central sections of the partitions are diaphragms 23, of leather or other iiexible material.

Referring now to the partitions in the lower cups 23 and 25, the numeral 29 designates the lower section of the partition, secured to the upper end of the tube 2, formed in its upper side with an angular passage 30, with which said pipe centrally communicates. Formed in the under side of the central section 31 is a corresponding passage 32, with which communicates through port 33 one section of a pipe 34, divided by a vertical partition 34a into two semicylindrical sections 35 and 36.

IOO

At the ends of said passage 32 are ports 37 and 38, port 37 communicating with the upper cup 23 through a port 39 in the upper section, provided with a valve 40, while port 38 communicates with one end of a curved passage 41 on the upper side of the central section. Port 38 is provided with a valve 42, while the other end of the passage 41 is provided with a port 43, communicating with the lower cup 25 by means of a port 45 in the lower section 29. The upper face of the central section is formed with a curved passage 47, having ports 4S and 49 at each end, closed by means of valves 50 and 51. Port 48 communicates with a curved passage 52 on the under side of the central section, having a port 53 at the opposite end communicating through port 54 in the upper section with cup 23. A passage 56 in the upper side of the lower section registers with passage 52. Port 49 communicates through port 57 in the lower section with cup 25. Passage 47 also communicates with the section or pipe 36 of the double pipe 34. The pipe 34 is connected at the upper end with a partition identical in all respects with the partition just described, eX- cept that part or section 36 communicates with passage 47 through port 58 in the central section oi' said partition, while pipe-section 35 communicates with passages 32 and 30. The partitionl on the upper series of pipes is identical with the partition in the series below, except that the passage 32 has no port 33.

The operation is as follows: Upon the downstroke of the cups water will be drawn into cup 25 through pipe 2 into passages 30 and 32, port 3S, (valve 42 opening,) passages 4l, and ports 43 and 45. At the same time water will be forced from cup 23 through ports 54 and 53, passage 52, port 48, (valve 50 opening,) passage 47 to section 36 of pipe 34, and from thence to the cups and partitions above, where a like operation will take place, and fromthe upper cups the water will be forced to the air-cham ber and out through the spout. Upon the upstroke of the cups water from the lower cups 25, 20, and 13 will be forced through ports 57 and 49 (valves 51 opening and valves 50 closing) to the passages 47, and from thence through pipe-sections 36 and pipe 1 to the air-chamber. At the same time water will be drawn into the upper cups through passages 30 and 32 and ports 37 and 39, the valve 40 opening. Upon the downstroke water will be drawn into the pipe-sections 35 and from thence through the passages and ports into the lower cups 13, 20, and 25, as before described.

From the above it will be seen that the pipe-sections 35 are for the purpose of feeding water to the different cups, while pipe-sections 36 are the ones by which the water is forced to the pump-tube 1 and air-chamber. These pipe-sections 35 and 36 are separate and independent in their action and may conwith, and said sections provided with ports, K

passages, and valves, verticallymovable semicylindrical cups through which said tubes pass, and a diaphragm and means for reciprocating said cups on the tubes, all operating substantially as shown in the application.

Having thus fully described my invention, what I claim is- 1. In a diaphragm-pump of the character described, the combination with the upper and lower pump-tubes, the vertically-reciprocating upper and lower cups each consisting of two semispherical sections, the three -part stationary partitionslocated in said cups, and provided with ports, passages and valves, and the diaphragms, of the intermediate cups, the stationary three -part partition located therein, provided with corresponding ports, passages, valves and diaphragm, the pipesections connecting the intermediate cups with the upper and lower ones, the rods connecting said cups and means for vertically reciprocating the cups, and said pipe sections being divided by a vertical partition into two compartments, one of which forms a common suction-pipe for the lower cups of the cup-sections, and the other, a common discharge-pipe for the upper cups of said cupsections substantially as specied.
